Abstract: PURPOSE: To obtain a ferroelectric FET element which has excellent processing accuracy, contact resistance and a memory modulation factor by deciding the end period of etching a ferroelectric layer by using the total resistance value of the ferroelectric layer and a semiconductor layer during etching. CONSTITUTION: A ferroelectric FET element which has at least semiconductor and ferroelectric element, a gate electrode 7 on the ferroelectric layer 3 and source and drain electrodes 8, 9 on the semiconductor layer 2 is manufactured. In this case, when the layer 3 of the source and drain electrode is removed by etching, the etching end period is decided by using the total resistance value of the layers 3, 2. For example, an La1.99 SrO0.01 CuO4 semiconductor thin film 2 and a (Pb0.95 5La0.05 ) (Zr0.2 Ti0.8 )O3 (PLZT) ferroelectric thin film 3 are formed on an SrTiO3 substrate 1.

Abstract: PURPOSE:To make it possible to precisely control the ignition timing even upon idling and as well low load operation, by providing such an arrangement that combustion pressure alone is separated from cylinder pressure and is detected so that the crank angle at which the combustion pressure comes to be maximum, is precisely detected. CONSTITUTION:Upon engine operation the pressure in each cylinder, which is obtained by processing the outputs of a crank angle sensor 1 and cylinder pressure sensors 2, before the top dead center during the compression stroke is stored in a memory means 3 at each predetermined crank angle positions. Then, a compressive pressure calculating means 4 calculates an objective waveform with respect the top dead center of the stored pressure waveform before the top dead center, and therefore, the compressive pressure at every predetermined crank angle position after the top dead center is calculated. Then, the output of the above-mentioned means 4 is subtracted from the output of the pressure sensor 2 at each predetermined crank angle positions so that combustion pressure at each predetermined angle positions after the top dead center is estimated, and thereafter, the crank angle theta at which combustion pressure becomes maximum, is obtained from the value obtained above, thereby the ignition timing is controlled so that the thus obtaind value thetam comes to a predetermined position after the top dead center.

Title: Production of flame-retarding styrene resin foam
Inventor: HAYASHI TOMOSHIGE
IPC: C08J9/14
Filed: 1988-03-30
Abstract: PURPOSE:To produce a styrene resin foam having flame retardancy and uniform fine cells, by adding a specified blowing agent and a specified flame retardant to a styrene resin, further adding a specified stabilizer to the mixture and extrusion-molding the resulting mixture by melt extrusion. CONSTITUTION:The title foam is produced by adding a halogenated aliphatic hydrocarbon (B) (e.g., monochlorodifluoromethane) as a blowing agent, a halogen-substituted eight-membered or larger cyclic alkane (C) (e.g., hexabromocyclododecane) or a halogen-substituted phenyl allyl ether derivative [e.g., tetrabromobisphenol A bis(allyl ether)] as a flame retardant to a styrene resin (A), further adding a phosphite ester (D) (e.g., diethyl phosphite) as a stabilizer to the mixture, and expansion-molding the resulting mixture by melt extrusion. In this way, a good foam can be obtained because a risk of a fire is decreased as compared with the case when the blowing agent is an aliphatic hydrocarbon, and component D added as a stabilizer common to components B and C can prevent the decomposition of the compounds and their interaction.
